In this case, the leading end of the film housed in the cartridge is made to protrude from the cartridge, a thin leader is attached to the projected end, and the film is fed into the developing device while being guided by the leader.

When all the films in the cartridge are fed into the developing device, the tail end of the film is cut off, and then a cartridge containing a separate photographed film is prepared. In order to supply film to a general developing device in this manner, a worker must be on standby to supply the photographed film, which is inefficient. On the other hand, when setting a large number of films in a developing device at once and developing them one after another, it is necessary to connect a large number of films in series in a light-shielded state.

SUMMARY OF THE INVENTION In view of the above facts, it is an object of the present invention to provide a film feeding device that can automatically and sequentially feed a large number of films to a processing device such as a developing device.

For this reason, in the present invention, it is only necessary to prepare a plurality of cassettes containing exposed film and load them onto the mounting bases, respectively, and the drive means moves the mounting bases one after another. let

The feeding means moves the lifted cassette on a mounting table and feeds it into the processing device. Therefore, the processing device can pull in the film in the cassette and perform processing such as development. In order to transfer the film in this cassette to a processing device, for example, a thin-walled leader may be attached to the leading end of the film, and this leader may be fed between the nipping and conveying rollers of the processing device.

After the film has been fed into the processing device, the feeding means returns the used cassette onto the mounting table.
The driving means again drives the conveying means to cause the cassette containing the undeveloped film to correspond to the feeding means. For this reason, the used cassettes that are further fed out from the feeding means in three directions are stacked and stored by the holding means. This holding means stacks and holds the used cassettes, which are sequentially sent upward by the conveying means, from the lower stage to the upper stage.
